4461por Loeffler, Johannes R., Fernández-Quintero, Monica L., Schauperl, Michael, Liedl, Klaus R.“…In computational drug design, the strength of stacking and the resulting optimization of the aromatic core or moiety is usually calculated using high level quantum mechanical approaches. However, as these calculations are performed in a vacuum, solvation properties are neglected. …”
